Thank you for understanding the lesson and sharing your assignment; I hope that you will enjoy this week's lesson and try to implement it in your life if you see any such case.

Observations

Task 1 (2.9/3)
You have shared a great knowledge about knee osteoarthritis and it's stages or grades. But you have to add the types of knee OA too to better explain this to other users. I appreciate your effort.

Task 2 (2.8/3)
In the second question, you tell us about how you assess the patient with knee OA by doing the physical examination, history taking, investigations, and special tests to assess meniscal tears. That's a good point if you add a special tests to add wear and tear around joint. Great.

Task 3 (3.9/4)
You try the heel slides, calf & hamstring stretch, William Flexion ( knee to chest exercise), Knee Isometric ( Knee flexion ). While performing calf & hamstring stretch try to self stretch by any band or cloth to increase stretch to hamstring. Remember always apply heating pad before performing these exercises. I appreciate your efforts.

Overall you made a good attempt to answer all the questions. I appreciate your efforts. But next time try to avoid the above written suggestions. Keep learning and try to implement your knowledge to the people suffering from any knee Osteoarthritis. Thank you.
